10 Claims.

My invention relates to convertible shallow well and deep well pumps and particularly to jet operated centrifugal pumps.

It is an object of this invention to provide a separation chamber which supports on one side a pump rotor and rotor housing together with an electric motor and on the other side a jet mechanism adapted to receive substantially air free fluid from the pump and deliver such fluid into the eye of the rotorof the pump thereby inducing the flow or water either irom a shallow well or deep well. 3

In particular, it is an object of this invention to provide a single opening in the side of the separation chamber casing for the reception of the ejector or for the reception of the piping connected to an ejector located remotely from the casing as in the case of a deep well. Heretofore, multiple side openings in the casing have been employed.

Another object of this invention is to provide a single standard opening so arranged as to receive either the ejector and associated piping for a shallow well or the piping of a deep well arrangement employing an ejector located'in the well. By employing a casing with an opening on one side for supporting a bracket which in turn supports the electric motor, the rotor and the pump casing and which supports on the other side the ejector and well piping, it is possible to maintain these essential parts in rigid position and alignment while at the same time providing a ready method of assembly and disassembly, low-cost construction and simple form of mechanism for conversion from a deep to shallow well or from a shallow wellto deep well arrangement.

It is a further object to provide a casing around the pump casing substantially equidistant from all parts thereof so as to employ a casing of the minimum practical size while retain n the feature of ready separation of water and air and of maintaining the pump in a self-primed It is a still further object to provide in this combination tangential passageways from the rotor of the pump through the pump casing into the air and water separation casing and to provide therewith an association of baflies and guides for breaking up continuous rotary movement of the discharge water so there will be a ready separation of the air and water.

Referring to the drawings:

Figure 1 is a perspective view, partially in section, showing the arrangement or this invention for shallow wells;

looking in the direction of the arrows and represents an alternative shallow well construction to that shown in Figures land 4.

Figure 4 is a similar view showing the arrangement of the ejector when the pump is used with a shallow well;

Figure 5 is a section on the line 5-5 of Figure 3 looking in the direction of the arrows;

Figure 6 is a section on the line 6--6 of Figure 4 looking in the direction of the arrows;

Figure 7 is a section on the line '|l of Figure 4 looking in the direction of the arrows;

Figure 8 is a view of the left-hand side of the pump as shown in Figure 4; and

Figure 9 is a vertical section through the pump as arranged for deep well operation.

Referring to the drawings in detail, I designates a well platform upon which is mounted the tank 2 containing the pumped water it. A float 4 regulates a valve 5 for the admission of air through the pipe 6. The pipe 6 is connected into the discharge casing at 'i'. The tank 2 is supplied with water from the pump through the pipe 8 connected to the top of the air and water separation or distribution casing 9. This casing 9 is provided with an opening In in which is mounted a motor supporting bracket H that is retained on the casing 9 by the bolts H. The outer end of this bracket at 13 supports the motor M. The bolts l5 attach the motor to the bracket. The inner end of the bracket is provided 5 with a shoulder it for supporting the pump casing ii. The pump casing l1 forms with the wall it of the bracket a pump chamber l9 in which the rotor 28 operates. The rotor 21! is connected by the coupling 2! to the armature shalt it of the motor M. A resiliently pressed seal generally designated 23 is mounted between t the rotor and the wall l8 of the bracket. The

exact nature of this seal is not important and, therefore, needs no detail description.

The rotor comprises a sleeve 24 forming a central passageway 25 which communicates with the radial passageways 2G in the rotor body an. These passageways 26 are formed by the ribs or guide vanes 21. The fluid passing throughthe eye of the rotor and radially and tangentially out of the rotor is delivered into the passageways 28 of the pump casing ll. The fluid thus delivered would continue to rotate within the casing 9 if it were not for the fact that in the bottom of the casing there are transverse bafiles as associated aaanm ribs -30 whichibreak nptne-mmticn rrne water and guide it upwardly therebythe air and water fsotheair rise tothe top of the casing s,- while the watetr-in. the bottom of the;

casing is substantially air free.

This water can then pass outwardly through.

the port 3i in the side of the casing 9. In the shallow well pump, as shown in Figures 1, 3, 4

and 7, the opening 3| is used as a support for the pipe 32 which in turn supports a coupling The pipe 34 communicates with a chamber 35 in the coupling 33. The water from the well passes around the chamber 36 formed by the housing 31 and thence through the passageway 38 into the interior of the ejector or Venturi tube 39.

The nozzle 40 is mounted in the casing 31 and is supplied with the pressure fluid from the easing 9. The flow of this fluid through the nozzle 40 into the ejector 39 induces the flow of the water from the shallow well.

The outer. end of the ejector or Venturi tube 39 is detachably mounted on the support 4!. This support is closely adjacent the eye of the rotor at 25 and is in sealing engagement with the rotor casing H. A seal 42 is provided to prevent pressure fluid from the casing 9 entering the eye of the rotor directly- It will be noted in Figures 3 and 4 that there is a modification of 33 that is connected to the well by the piping 34-.

the method of mounting the ejector or Venturi tube 39 but the principle of operation remains the same.

Turning to the arrangement for the deep well, as shown in Figures 2 and 9, it can be observed that the opening 3| is provided with a right angle casting which is threaded into it. This casting or coupling means is designated 43. An aperture 44 in this casting receives the pipe 45, one end of which is threaded into the bracket M in the casing 9. The Venturi tube of the ejector 39 has been unscrewed from the bracket 4| and the pipe 45 has been substituted therefor.

The pipe 45 is sealed to the casting 43 by the gasket 46. The other end of the pipe 45 is connected to the ejector assembly comprising the Venturi tube 39 of the ejector and the nozzle 4!]. Fluid is supplied to the nozzle 40 by the pipe 47 which is connected to the lower portion of the casting 43 as at 48 and is arranged to take substantially air free water from the bottom of the casing 9 as it has been discharged by the pump.

The numeral BI in 'Figs. 1, 2, 4 and 9 indicates webs which connect 4! to casing9 respectively.

It will be noted from this arrangement that the major portion of the apparatus is undisturbed when making the conversion froma shallow well to deep well or from a deep well to shallow well. The conversion is effected by removing the pipe 32 and the Venturi or ejector tube 39 and substituting the casing 43 and connecting the pipe 45 in the place of the Venturi tube 39. By having a single opening instead of a dual opening, it is possible to simplify, under some conditions, this conversion.

Turning to Figure 3, which shows an alternative construction of a shallow well pump, the primed numerals indicate corresponding parts to those shown .in Figures 1 and 4. It will be appreciated that the form of the invention shown in Figure 3 is as well adapted for conversion to a deep well pump as is that of Figures 1 and 4. Pipe 32 and ejector 39 may be unscrewed from their supports and casing 43 and pipe 45 may be wed in their places respectively, thereby confrom ashallow to a deepnwnrbe. understoodthat 1 desire a. comma-- hand. withln' myi'nvention-such: modifications as cOInQWii-Hin the scopeofthethe appended claims.
